Spot Checks
This chapter explains how to check for problems and solve them.
It is good practice to carry out regular checks of your LinkBuilder
MSH equipment.
Check the following:
■
LEDs
Press the LAMP TEST button, on the LinkBuilder MSH's Display
Panel. All yellow LEDs should light continuously and all bi-color
LEDs should flash red/green alternately.
■
Cabling
Check that all external cabling connections are secure and that no
cables are pulled taut. All AUI cables should be secured by the
fitted slide locks.
■
Modules
Check that all modules are secured in position and that their
ejectors are locked. All modules should be flush with each other.
If individual LEDs do not respond to the lamp test, then the LEDs
are at fault. However, if all a module's LEDs do not respond, and
all other checks are satisfied, then there is a fault with either the
module or the LinkBuilder MSH chassis. In both cases, see
